Here I describe how I installed '''Lubuntu-12.04''' on my '''Lenovo E600A''' laptop.<<BR>>
Hope that will be helpful to someone.

= My Lenovo laptop =
Model: Lenovo E600A<<BR>>
CPU: Intel Centrio (PentiumM 1.6GHz)<<BR>>
Memory: 768MB<<BR>>
GPU: nVIDIA Geforce FX go 5200<<BR>>
HD: 38GB, C:--NTFS 10GB, D:--FAT32 10GB, FreeSpace: 17GB<<BR>>
OS: WindowsXP SP4 on C:<<BR>>
DVD-ROM: Yes, bootable<<BR>>
USB: Yes, but not bootable<<BR>>

I wanted to install Ubuntu 14.04 co-hosting with my WindowsXP at first.<<BR>>
After failed with the bootable-DVD of Ubuntu 14.04, I know that my CPU '''does not support PAE'''.
= Which release fit my machine? =
From [[https://help.ubuntu.com/community/Lubuntu/Documentation/MinimalInstall|here]] I know the best one for my Lenovo-E600A is Lubuntu 12.04.<<BR>>
After recording 2 DVD-ROMs of Ubuntu14.04 and Ubuntu12.04-nonPAE and failed both, I decided to install from HardDisk.<<BR>>
Then I get __lubuntu-12.04-desktop-i386.iso__ [[http://cdimages.ubuntu.com/lubuntu/releases/precise/release/|here]].
= Tools for install from Hard Disk =
The installation will begin from the existing OS WindowsXP.<<BR>>
Only the ''' grub4dos''', I found the grub4dos-0.4.4.<<BR>>
Of course, the package tool, such as '''7zip'''.
= Preparation for Installation from Hard Disk =
 *Start my E600A into Windows XP.
 *Put the ISO file to the root of "d:" (FAT32 disk)
 *Extract directory __casper__ from the ISO file to the root of "d:"
 *Copy file __grldr__ to the root of "C:" (the boot disk of Windows XP)
 *Creat a file named __menu.lst__ with following content:
  title Install Lubuntu<<BR>>
  root (hd0,1)<<BR>>
  kernel /casper/vmlinuz boot=casper iso-scan/filename=/lubuntu-12.04-desktop-i386.iso ro<<BR>>
  initrd /casper/initrd.lz<<BR>>
 *Edit the windowsXP's __boot.ini__ file at root of "C:" to add the following line:
  C:\grldr="GRUB DOS"<<BR>>

= Installation procedure =
 *Restart my laptop E600A
 *At the startup menu, choose "GRUB DOS"
 *At GRUB menu, choose "Install Lubuntu"
 *Then you will see the GUI with "try Lubuntu" and "Install Lubuntu"
 *Select "try Lubuntu", you will get into the live Lubuntu desktop.
 *Press "Ctrl+Alt+T" to open a terminal
 *In the terminal, run "ls -l /isodevices", you can find it's your "C:" disk.
 *In the terminal, run "sudo umount -l /isodevice"
 *Double click the "Install Lubuntu" icon on the desktop (It's the only icon).
 *Then follow the normal installation steps [[https://help.ubuntu.com/community/Lubuntu/InstallingLubuntu|InstallingLubuntu]]
 *Select "Install Lubuntu along with WindowsXP"
= Important notes =
 1. My WindowsXP's "C:" is NTFS format. It will not work if I put ISO file on "C:".
 1. My "D:" is FAT32 format maybe that is the key fact for me to do it successfully.
 1. Don't forget to umount the /isodevice, or the installation will be pending at partitioning.
 1. After installation, If you find the Lubuntu's GRUB multi-boot menu font size is too big or too small <<BR>>
 You can try: <<BR>>
 Edit "GRUB_GFXMODE=640x480" in file __/etc/default/grub__ with your real LCD size.<<BR>>
  sudo vi /etc/default/grub <<BR>>
 Then update it: sudo update-grub
